HYDROCARBON-IBURNER.

Specification of Letters Patent.

Application filed January 14,1911. Serial No. 602,730.

To all'whom it may concern:

. Be it known that we, ORLO F. SHEARMAN and CHARLES F. ERDMANN, citizensof the The object of the invention is to provide a hydrocarbon burner ofthis character in which the liquid fuel is mixed with air prior to itspassage into the vaporizer.

A further object is the provision of means whereby air under pressuremay be used for feeding the proper quantity of air to be mixed with theoil and also be used as a means for forcing the oil into the vaporizer.

A further object is to provide a vaporizer and burner of this characterwhich may be readily cleaned by forcing the compressed air through thetubes of the vaporizer and out through the openings of the burner,thereby clearing the pipes and passages of the burner from soot or otheraccumulations of foreign 'particles.

A further object is to provide the combination with a vaporizing burnerof a flame-. deflecting plate supported immediately over the vaporizerand burner, so arranged that it will deflect the flame from the burneroutward and around the circumference of the plate, the deflecting platebeing so formed that a section of it may be removed in order to permitthe ,primary ignition of the gas.

A still further object'is the provision of a combined priming cup andburner located below the vaporizer and so arranged that the jets arisingfrom the burner will play around the coils forming the vaporizer so asto obtain a maximum application of heat to the vaporizer.

Our invention is illustrated in the accompanying drawings wherein:

that the vaporizer 2 comprises a conical volute formed of a metal pipeor tube, the

apex of the volute being downward. The

extremity of the coil forming the vaporizer is-carried downward as at 3and terminates in a burner 4, this burner preferably having the form ofa cylindrical chamber provided upon its upper face and surrounding thepipe 3 with a plurality of jetopenings 5, Preferably formed integralwith the burner or chamber 4 is the priming cup 6 which is, of course,larger in diameter than the burner 4 and is of sufficient depth tocontain a properamount of fuel for priming. The upper end of the coil 2forming the vaporizer extends outward at a tangent as at 7 and passesthrough the walls of the stove orfurnace A. The pipe 7 is connected to aT 8, one branch of which is connected to a fuel supply pipe 9, 'whilethe other arm of the directly opposite to the pipe 7 is connected to apipe '10 which passes to an elbow 11 from which a pipe 12 extends to acompressed air tank 13. The T 8is provided with a valve 14 whereby theadmission of fuel from the pipe 9 to the pipe 7 may be regulated. Theelbow 11 is alsov provided with a needle valve 15 whereby the passage ofair from the pipe 12 to the pipe 7 may be controlled. The supply pipe 9extends into an oil tank or other suitable fuel reservoir 16.Preferably, the pipe 9 extends to the bottom of the tank 16 asillustrated in Fig. 1; The tank '16 is connected to the compressed airtank 13 by means of a pipe 17 which extends from the upper end of thetank 16 and is provided with a valve 18 13 and 16 may be established orcut off. The tank is further provided with a filling opening 19. Thecompressed air tank 13 is connected, preferably at itsupper end, bymeans of a pipe 20 to any suitable air compressor, as for instancean-air pum not shown, and the pipe 20 is provided with a wherebycommunication between the tanks valve 21 whereby communication may beestablished between or cut -off between the air pump and the compressedair tank 13.

v about an inch space is left between the pcriphery of the deflectingplate 23 and the walls of the stove orfurnace. Eccentrically disposed intheplate 23 is an opening 24 normally closed by a lid or removablesection 25, the margin of the plate 23 immediately around the opening 24being deflected to form an annular flange upon which the lid 25 issupported. The lid 25, is provided with a recess 26 whereb an implementmay be applied to raise t e lid. The

deflectin plate 23 is supported in any suitg of heat and for an increasein the heating able manner but preferably by means of supporting boltsor studs 27 extending upward from the uppermost eoil of the vaorizer 2.Nuts on these bolts hold the deecting plate in position but permit thefdeflecting plate to be easilywemoved when' desired. In order to hold thedeflecting; plate, the vaporizer and the burner in proper relativeposition within the stove or furnace, we preferably provide one or morehookshaped bolts 28 which pass through the walls of the furnace orheaterand'have upwardly extending terminal portions which: pass upthrough openings formed in fhe margin of the deflecting plate. Thesebolts 28 hold the deflecting plate in proper position so as to leave aspace between the pe-'; riphery of the deflecting plate and the wali' ofthe stove or heater.

In practice, when it is desired to start our improved burner, the valves14 and 15 are closed and the valves 18 and 21 opened: and the air in thecompressed air tank13 and supply tank 16 compressed to any dew sireddegree. After the desired pressure has been secured in the tanks, thevalve 21 is closed. It will now be seen that there is pressure of airupon the upper surface of the oil contained within the tank 16. The

valve 14 is now opened and oil passes from the tank 16 through the pipe9, the T 8 to 55 The liquid fuel passes down these coils of pipe and isforced out through the openings the coils of pipe forming the vaporizer.

so forced out accumulates in the priming cup 6. When the priming, cup isnearly full of oil, the valve 14 is'closed and the oil in the a cup 6 islighted. When the oil is nearly burned out of the priming cup, the valve14 is opened a slight amount and when the oil igmtes from the flames inthe priming' cup then'the'valve 15 is o ened a slight amount.

When it is desired to ignite the oil in the priming cup, it is onlynecessany to remove the section 25 of the deflecting plate. A match maythen be easily applied to the oil in the riming cup. The deflectingplate causes t e flames to pass up adjacent to the wall of the stove,furnace or other heater and thus provides for a better distributionpower of the .stove or furnace. It will be seen that ,the flamesproceeding fromthe orifices 6 willlay over, around and between the pipeormingthe vaporizing coil 2 so that a particularly effective applicationof heat occurs for the proper vaporization of the fuel before it passesto the burning orifices. It is further to be noted that air is admixedwith the fuel prior to its passage eat is produced. I

to be noted that the air is forced into the 4 T 8 under pressureandtends to nebulize the oil as it passes into the vaporizer.

It will be observed that the vaporizer being in the form of an invertedconlcal volute, tends to deflect the flames arising from the burner 5upward and outward to the circumference of the deflecting plate 23 andbetween the periphery of the deflecting plate and the walls of theheater A. At the same time some of the flames will play upward withinthe space inclosed by the tubular vaporizer and between the coils of thevaporizer so that the vaporizer will be thoroughly heated. It is furtherto be noted that when the air pressure has been entirely exhaustedwithin the tank 13 the oil will no longer be forced into the burner andhence that the fire will go out.

By connecting the compressed air'tank '13, both with the 011 tank 16 andwith the T 8,- we secure a positive feed of oil to the burner and alsosecure a positive feed of air thereto.- The amount of compressedair'within the tank 13 may be easily adjusted so as to cause the burnerto operate for any desired length. oftime.

a vaporizing coil having the form of an mverted conical volute, a burnerlocated below the apex of the coil and connected with the same, saidburner having jet openings directed toward the coil, a pruning cupsurrounding the burner, a fuel inlet pipe connected to the upper end ofthe coil, and a deflecting plate supported above the upper end of thecoil and slightly larger in diameter than the same, said deflectingplate formed in sections.
